Abstract

The disclosure describes a method and system that allows a user to configure electrical stimulation therapy by defining a three-dimensional (3D) stimulation field. After a stimulation lead is implanted in a patient, a clinician manipulates the 3D stimulation field in a 3D environment to encompass desired anatomical regions of the patient. In this manner, the clinician determines which anatomical regions to stimulate, and the system generates the necessary stimulation parameters. In some cases, a lead icon representing the implanted lead is displayed to show the clinician where the lead is relative to the 3D anatomical regions of the patient.

Claims

1. A method comprising:

receiving, by a processor, a user input defining a first target area of a patient tissue to receive electrical stimulation therapy;

modifying, by the processor and based on a characteristic of the patient tissue within the first target area, the first target area of the patient tissue to a second target area of the patient tissue;

determining a position of an electrical stimulation lead relative to the second target area of the patient tissue; and

determining, by the processor and based on the second target area and the position of the electrical stimulation lead, a set of electrical stimulation parameters that define electrical stimulation therapy deliverable to the second target area.

2. The method of claim 1, wherein the characteristic comprises a density of the patient tissue.

3. The method of claim 1, further comprising presenting, by a user interface, a graphical representation of the characteristic of the patient tissue.

4. The method of claim 3, wherein different values of the characteristic of the patient tissue are represented by different respective colors.

5. The method of claim 1, wherein receiving the user input comprises receiving an outline of the first target area with respect to the patient tissue via a user interface.

6. The method of claim 1, wherein the user input comprises selection of a value of the characteristic.

7. The method of claim 6, wherein selection of the value comprises selection of a range of values of the characteristic, wherein the range of values comprises the value.

8. The method of claim 1, wherein modifying the first target area comprises modifying, based on a selected value of the characteristic, the first target area to the second target area that includes tissue areas having the selected value.

9. The method of claim 1, wherein modifying the first target area to the second target area comprises defining the second target area to include one or more anatomical regions of the patient tissue having a second value of the characteristic that corresponds to a first value of the characteristic of at least a portion of the first target area.

10. The method of claim 1, wherein the user input is a first user input and the set of electrical stimulation parameters is a first set of electrical stimulation parameters, and wherein the method further comprises:

receiving a second user input modifying the second target area to a third target area; and

determining, based on the third target area and the position of the electrical stimulation lead relative to the third target area, a second set of electrical stimulation parameters that define electrical stimulation therapy deliverable to the third target area.

11. A system comprising:

a processor configured to;

receive an a user input defining a first target area of a patient tissue to receive electrical stimulation therapy;

modify, based on a characteristic of the patient tissue within the first target area, the first target area of the patient tissue to a second target area of the patient tissue;

determine a position of an electrical stimulation lead relative to the second target area of the patient tissue; and

determine, based on the second target area and the position of the electrical stimulation lead, a set of electrical stimulation parameters that define electrical stimulation therapy deliverable to the second target area.

12. The system of claim 11, wherein the characteristic comprises a density of the patient tissue.

13. The system of claim 11, further comprising a display, wherein the processor is configured to control the display to present, via a user interface, a graphical representation of the characteristic of the patient tissue.

14. The system of claim 13, wherein different values of the characteristic of the patient tissue are represented by different respective colors.

15. The system of claim 11, wherein the processor is configured to receive, as at least a portion of the user input, an outline of the first target area with respect to the patient tissue via a user interface.

16. The system of claim 11, wherein the user input comprises selection of a value of the characteristic.

17. The system of claim 16, wherein selection of the value comprises selection of a range of values of the characteristic, wherein the range of values comprises the value.

18. The system of claim 11, wherein the processor is configured to modify the first target area by modifying, based on a selected value of the characteristic, the first target area to the second target area that includes tissue areas having the selected value.

19. The system of claim 11, wherein the processor is configured to modify the first target area to the second target area by defining the second target area to include one or more anatomical regions of the patient tissue having a second value of the characteristic that corresponds to a first value of the characteristic of at least a portion of the first target area.

20. The system of claim 11, wherein the user input is a first user input and the set of electrical stimulation parameters is a first set of electrical stimulation parameters, and wherein the processor is configured to:

receive a second user input modifying the second target area to a third target area; and

determine, based on the third target area and the position of the electrical stimulation lead relative to the third target area, a second set of electrical stimulation parameters that define electrical stimulation therapy deliverable to the third target area.

21. A computer-readable storage medium comprising instructions that, when executed, cause a processor to:

receive a user input defining a first target area of a patient tissue to receive electrical stimulation therapy;

modify, based on a characteristic of the patient tissue within the first target area, the first target area of the patient tissue to a second target area of the patient tissue;

determine a position of an electrical stimulation lead relative to the second target area of the patient tissue; and

determine, based on the second target area and the position of the electrical stimulation lead, a set of electrical stimulation parameters that define electrical stimulation therapy deliverable to the second target area.
